2,4,6-trinitrophenol

2,4,6-trinitrophenol is a highly explosive organic compound with the molecular formula C6H3N3O7 and CAS number 88-89-1. Also known as picric acid, it belongs to the nitroaromatic family and has a molecular weight of 229.1 g/mol. This crystalline substance is classified as an explosive material (Class 1.1) and presents acute toxicity hazards, making it extremely dangerous to handle without proper safety measures.

2,4,6-trinitrophenol appears as yellow crystalline solid with a bitter taste. It has a melting point of approximately 122°C and is moderately soluble in water (approximately 1.2% at 20°C), more soluble in hot water, alcohol, and acetone. The compound is sensitive to shock, friction, and heat, making it highly unstable. Its explosive nature is due to the three nitro groups attached to the benzene ring.

2,4,6-trinitrophenol is primarily used in military applications as an explosive and in ammunition manufacturing. In industrial settings, it serves as an intermediate in the synthesis of other chemicals and as a laboratory reagent for analytical purposes. It's also used in the production of certain dyes and in metallurgy for etching metals. Due to its extreme hazards, its use is highly regulated and restricted to specialized applications.

2,4,6-trinitrophenol requires extreme caution during handling due to its explosive nature. Essential safety measures include wearing full protective equipment (chemical-resistant gloves, safety goggles, protective clothing), working in well-ventilated areas away from heat sources, and avoiding friction or impact. Only trained personnel should handle this substance. Use non-sparking tools, ground all equipment, and maintain emergency procedures readily available. Never handle dry material as it becomes extremely shock-sensitive.

2,4,6-trinitrophenol must be stored in specialized explosive storage facilities meeting regulatory requirements. Keep containers tightly sealed in cool, dry conditions away from heat, ignition sources, and incompatible materials like metals, strong bases, and reducing agents. The storage area should be well-ventilated, temperature-controlled, and equipped with appropriate fire suppression systems. Regular inspection for crystallization or deterioration is essential, as dried material becomes extremely dangerous.

Immediate action is required for any contact with 2,4,6-trinitrophenol. For skin contact, remove contaminated clothing and flush thoroughly with water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention. For eye contact, rinse continuously with water for 15 minutes and remove contact lenses if present. In case of ingestion, do not induce vomiting and seek immediate medical care. Always contact emergency services for any significant exposure.

2,4,6-trinitrophenol disposal requires specialized hazardous waste management due to its explosive classification. Contact licensed hazardous waste disposal companies experienced in handling explosive materials. Never attempt disposal through normal waste streams or sewage systems. The material typically requires controlled detonation or specialized chemical treatment by qualified professionals. Ensure compliance with local, national, and international regulations for explosive waste disposal, including proper documentation and transport requirements.

2,4,6-trinitrophenol is classified as dangerous goods under ADR regulations, falling into Class 1 (explosives) transport category. Transportation requires specialized explosive transport licenses, appropriate UN specification packaging, and compliance with quantity limitations. Only certified carriers experienced in explosive materials transport should handle shipments. Proper documentation, labeling with GHS01 and GHS06 pictograms, and emergency response information must accompany all shipments. Route planning must avoid populated areas where possible.

2,4,6-trinitrophenol is subject to extensive regulations due to its explosive and toxic properties. Under EU CLP regulation, it carries GHS01 and GHS06 pictograms with 'Danger' signal word. REACH registration requirements apply for commercial use. Additional explosive regulations, import/export controls, and security measures are mandatory. Many countries restrict or prohibit its civilian use, requiring special licenses for possession and handling. Workplace exposure limits and environmental discharge restrictions also apply.

2,4,6-trinitrophenol is available through specialized chemical distributors like OYSI, which serves European markets with technical-grade chemicals. Due to its explosive classification and regulatory restrictions, purchases require proper licensing, end-user declarations, and compliance verification. OYSI can provide guidance on regulatory requirements and proper handling procedures. Availability is strictly controlled and limited to legitimate industrial, research, or military applications with appropriate authorizations and safety protocols in place.
